RUDOLPH FEDERROLL, OF NEW YORK, N. Y.

OIL-TANK.

v SPECIFICATION forming part of Letters Patent No.352,914, dated November 23, 1886'.

' Application filed September 23, 1886. Serial No. 214,334. (No model.)

To all whom'z't may colecerm- Be it known that I, RUDOLPH FEDERROLL a resident of New` York city, in the county and State of New York, have invented an Improved Oil rIank and Pump, of which the fol= lowing is a "full, clear, and exact description, reference being made to the accompanying drawings, in which- Figure l is a vertical central section of my improved oiltank having a pump, the line x x, Fig. 2, showing the plane of section. Fig. 2 is a top View ot' said tank. Fig. 3 is a bottom view of the same. Fig. 4 is an enlarged vertical section showing the connection of the bot-tom of the tank with the side walls. Fig. 5 is an enlarged vert-ical section 'showing the means for securing the strainer'. Fig. 6 is a detail section through the tube of the pump, showing how the parts of the same are united to the carrying-frame.

This inventiongrelates to certain improvements inthe construction of metallic oil-tanks, being tanks intended to contain petroleum or the like, and a pump, with the aid of which a dealer can supply the consumer with limited quantities of the intlammable liquid.

The principal object of the invention is to Irender such a tank lire-proof, and also to make it compact for convenience in transportation.

The invention` consists, first, in supplying such a tank with a reversible top,which,when in place for use, carries the diaphragm which separates the oil-containing chamber from the upper pump-chamber, and which hasa movv able lid for also closingthe upperpump-chamber.

. The invention also consists in a`new means for securing the strainer lto the diaphragm, and in a new construction of sectional pump-body in combination with said diaphragm, all as hereinafter more fully described and claimed.

In the drawings, Vthe letter A represents the vertical wall of my improvedoil-tank. B is the bottom of the same, and C the top. V- The bottom B, which is made of sheet metal, has its edges turned down, as at a, (see Fig. 4,) so that said vertical portion a of the bottomshall come in contact with the inner side of the vertical Wall A. A cast-metal trough-like plate,

5o D, receives this double lower portio'nof the tank in its cavity, as is also shown in Fig. 4,

and serves likewise to support with its inner Wall, b, the outer part of the bottom proper, B. Fig. 3 shows a bottom View of the trough D,

representing it siipplied with series of braces d,- for giving it increasedstrength. f Fig. 3 rep-A resents this `bottom trough, D,.as Of circular form; but it may be of angular or Oval form,

.if desired.

Into the upper part of the vertical body A of the tank, which is supplied witha proper screw-thread, e, is screwed the top piece, C. rIhis top piece consists of a threaded vertical wall,f, having outwardly-projecting lip g, and of the lower plate or diaphragm, h. Thetop piece, G, is screwed into the body A until the is showny by full lines in Fig. 1, or it can be,

turned, as shown by dotted lines mx, so that the entire tank will be closed by the two lids Z and m. To facilitate this turning I provide the movable half-lid m-with a threaded portion, n, which matches the upper partof the threaded portion f of the top C. In other words, a threaded ring, n, surrounds the up- 'per part of the threaded ring f and carries the movable half-lid m, allowing the same to .be turned either over the rigid half-lid l, as by full lines in' Fig. l, or over the otherwise uncovered portion of the tank, as by dotted lines A mx in Fig. 1.

In transporting the tank I unfasten the top C and turn it upside down, so as to bring the diaphragm h to the top of the tank and the lids lm into the body thereof. This is indicated by dotted lines'in Fig. 1 and results in saving much room during transportation'.

The diaphragm his provided with-astrainer, o, which is fastened to said diaphragm by the means more clearly shown in Fig. 5 -that is to say, the strainer proper is cup-shaped, the upright portion 10 ofthe cup being screwthreaded.

This cup-shapedkstrainer is placed against theunder side of the diaphragm h, while from the top of said-diaphragm a screw-ring, q, is in- IOO 1 serted to engage with the threaded part p, thus holding the strainer in place; yet at any time,

by simply unscrewing the ring q, the strainer Y can be detached and alarge man-hole obtained, through which the interior of the tank can be inspected and repaired. The pump-body Eis also madein sections, that are'secured against the diaphragm h, as appears very clearly in Fig. 6 of the drawings-that is to say, the lower section, r, of the pump has a flange, s, which lies against the under side of the diaphragm h, While the upper portion, t, of the pump has a iiange, u, that lies against the upper surface tion f and diaphragm h, substantially as and for thepurposespecied. f

3. The combination of the tank body A, having threaded portion @,With the top C, having threaded portionf and rigid half-iid l, and with the threaded ring n and movable half-lid an, substantially as hereinshown and described.

4. The combination of the diaphragm h with the cup shaped strainer o,having threaded upright portion p, and with the screw-ring q, substantially as and for the purpose herein shown and described.

5. The sectional pump E, consisting of the `lower threaded portion, r, having flange s, up-

per portion, t, having flange u, and screw-ring o, in combination with the diaphragm h, against which the flanges s u are drawn when the sections are united by thescreW-ring, substa ntially as herein shown and described.
